Laravel 9 composer syntax error, unexpected mark ")"

Question

After running composer update in my Laravel 9 project, I encountered the following error message:

Writing lock file
Installing dependencies from lock file (including require-dev)
Package operations: 0 installs, 1 update, 1 removal
  - Downloading fruitcake/laravel-cors (v3.0.0)
  - Removing asm89/stack-cors (v2.1.1)
  - Upgrading fruitcake/laravel-cors (v2.2.0 => v3.0.0): Extracting archive
77 package suggestions were added by new dependencies, use `composer suggest` to see details.
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover --ansi

In Finder.php line 588:

  syntax error, unexpected token ")"


Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

It seems the update completed, but something went wrong and now in the console I get a syntax error, unexpected tag ")" Error on Finder.php: 588.

I checked the file and it looks correct.

When I open the project in the browser, I get this error:

Fatal error: Uncaught RuntimeException: A facade root has not been set. in /var/www/html/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php:334

I also cleared bootstrap/cahce/ and storage/framework/cache/data/, storage/framework/sessions/, storage All caches in the /framework/views/ folder.

I am using PHP version 8.0.16.

Composer version 2.0.12 2021-04-01 10:14:59.

Any idea how to solve this problem?

Answer 1

To continue using php 8.0, please add these entries to your composer.json

"require": {
        ...
        "symfony/console": "6.0.*",
        "symfony/error-handler": "6.0.*",
        "symfony/finder": "6.0.*",
        "symfony/http-foundation": "6.0.*",
        "symfony/http-kernel": "6.0.*",
        "symfony/mailer": "6.0.*",
        "symfony/mime": "6.0.*",
        "symfony/process": "6.0.*",
        "symfony/routing": "6.0.*",
        "symfony/var-dumper": "6.0.*",
        "symfony/event-dispatcher": "6.0.*",
        "symfony/string": "6.0.*",
        "symfony/translation": "6.0.*",
        "symfony/translation-contracts": "3.0.*",
        "symfony/service-contracts": "3.0.*",
        "symfony/event-dispatcher-contracts": "3.0.*",
        "symfony/deprecation-contracts": "3.0.*",
        ...
    }

Used php 8.0 and Laravel 9 for me.

Answer 2

I found a solution:

1. Upgrade to PHP 8.1
2. Run docker pullcomposer to upgrade to the latest version of composer (from 2.0 to 2.2)
3. Run in Docker container composer update
